Applied optics, 1996•opg.optica.orgWe have investigated the effects of laser bandwidth on quantitative cavity ring-down
spectroscopy using the rR transitions of the b (υ= 0)? X (υ= 0) band of molecular oxygen. It is
found that failure to account properly for the laser bandwidth leads to systematic errors in the
number densities determined from measured ring-down signals. When the frequency-
integrated expression for the ring-down signal is fitted and measured laser line shapes are
used, excellent agreement between measured and predicted number densities is found.
